Lithium Niobate (LN) tioata he teitei polarization māhorahora (0.70 C/m² i te pāmahana rūma) ā, he karaihe ferroelectric me te teitei o te pāmahana Curie (1210 ℃) i kitea i tenei wa. E rua nga ahuatanga o te karaihe LN e kukume ana i te aro motuhake. Tuatahi, he maha nga paanga o te whakaahua hiko, tae atu ki te paanga piezoelectric, te hiko-optic effect, te kore-linear optical effect, te photorefractive effect, te photovoltaic effect, te photoelastic effect, te acoustooptic effect me etahi atu taonga photoelectric. Tuarua, ko te mahi o te karaihe LN he tino whakarite, he mea na te hanganga lattice me te nui o te hanganga hapa o te karaihe LN. He maha nga ahuatanga o te karaihe LN ka taea te whakahaere nui e te titonga karaihe, te doping huānga, te mana o te kawanatanga valence me era atu. I tua atu, ko te karaihe LN he taonga i roto i nga rauemi mata, ko te tikanga o te kounga teitei me te rahi o te karaihe kotahi he mea ngawari ki te whakarite.

Ko te karaihe LN he mea pumau me nga taonga matū, he ngawari ki te tukatuka, te whanui o te waahanga whakawhiti marama (0.3 ~ 5).μm), me te nui birefringence (mo te 0.8 @ 633 nm), he ngawari ki te hanga hei arataki ngaru whatu kounga teitei. Na reira, ko nga taputapu optoelectronic e pa ana ki te LN, penei i te tātari ngaru oro oro mata, te whakarereke marama, te whakahuri i te wahanga, te whakawehe whatu, te whakahuri Q-hiko (www.wisoptic.com), ka akohia me te whakamahi ki nga mara e whai ake nei: hangarau hiko. , hangarau whakawhitiwhiti whatu, hangarau laser. I tata nei, me nga pakaruhanga i roto i te tono o 5G, micro/nano photonics, integrated photonics me quantum optics, LN tioata kua aro nui ano. I te tau 2017, i kii a Burrows o te Whare Wananga o Harvard ko te waa o“awaawa lithium niobate” kei te haere mai inaianei.
